HAY-CARRIER.

Specification of Letters Patent.

Patented. Nov. 6, 1906.

To ail whmn it may concern:

Be it known that I, HENRY L. FERRIs, a citizen of the United States ofAmerica, residing at Harvard, in the county of lWIcI-Ienry and State ofIllinois, have invented certain new and useful Improvements inHay-Carriers, of which the following is a specification.

My invention relates to improvements in hay-carriers, and is fullydescribed and explained in this specification and shown in theaccompanying drawings, in which Figure 1 is a side elevation of myimproved device. Fig. 2 isa section in the line 2 2 of Fig. 4, theinterior parts of the device being shown in elevation. Fig. 3 is a sideelevation of the rope-clamping jaws. Fig. 4 is a rear elevation of thedevice. Fig. 5 is a section in the line 5 5 of Fig. 1. Fig. 6 is asection in the line 6 6 of Fig. 1. Fig. 7 is a horizontal section in theline 7 7 of Fig. 1. Fig. 8 is a horizontal section in the line 8 8 ofFig. 1, and Fig. 9 is a top plan of the pulley-supporting member andclamping device.

Referring to the drawings, A is a track bearing a trip-block a. Upon thetrack A runs a carriage B, supported by pulleys b and having at itslower end a circular turn-table B,

to which is swiveled a frame composed oftwo side plates C C, bolted orotherwisesecured together to form a hollow structure. Between the partsof the frame is pivoted by gudgeons (l a pulley-supporting member D,made in the form of a bell-crank lever, the rear of which issubstantially horizontal when the device is in its normal position andthe front arm of which extends diagonally upward from the gudgeons (l.The rear arm of this pulley-supporting member is provided withdownwardly-extending ears (1, between which runs a shaft bearing twomain sheaves or ulleys (1 (1 Above and in line with the pullley d is aguide-pulley d on the pulley-supporting member, said pulley running upona diagonally-inclined axis, as illustrated.

The rear end of the pulley-supporting member D is bifurcated andstraddles the lower portion of an engagement-piece E, having a slot 6,through which passes a pin (1 on the The engage-' in the ordinarymanner, which is fully described and illustrated in my application forpatent on hay-carriers filed on even date herewith and allotted SerialNo. 278,323, and this engagement-piece is engaged by a dog F, operatedby a fork G, connected with a tri -lever H, exactly as set forth in saidapplication.

X indicates the rope of my device, andthe same enters the carrier at itsfront end. It will be seen that the front arm of thepulley supportingmember is bifurcated, Figs. 8 and 9, and the rope passes between the twoportions thereof. The rope is first led over the guide-pulley (1 thendown over the main prulley d thence under two sling-pulleys Y thencedown to the sling-pulley Y. It is to be noted that the two main pulleysare pivoted in the exact center of the pulley-supporting member, so thata central pull is given thereto even if the re es drag unequally on thetwo pulleys. In t is way the pivots of the pulley-sup orting member u onthe frame are relieve of any strain'whic might otherwise arise. It willbe seen by the arrangement herein described the rope is given a bight atright angles to the frame andtrack and that the main pulleys lie in-theplane of this bight, so that the rope lengths may be drawn laterally toany extent without danger of running off the pulleys. Furthermore, thepulleys are brought close together, and space is economized, and inaddition one pivot-pin is utilized for both, thereby saving machine-workand hand-labor in construction. A rope-guide D is provided on thepulley-su porting member D to prevent the accidenta running off of therope from the main pulleys.

The operationof the tripping device here shown will be readily apparent,and no furthence over the main pulley d and ther description of it willbe necessary. The 5 portion of the frame of the device is pivoted alower clamping-jaw I, the form and construction of which is wellillustrated in Figs. 2 and 3. This j aw is straddled and inclosed by anupper clamping-j aw J, pivoted at j to the frame of the machine. Thisupper jaw J is trough-shaped and has a corrugated inner face forengagement with the rope. This upper clamping-jaw is also provided withslots j, in which run pins i on the lower clamping-jaw, the arrangementbeing such that the clamping-j aw J is rotated about its pivot, andconsequently swung downward and backward from the position shown in Fig.1 to the position shown in Fig. 2, the jaw I will swing with it, movingupward and backward. The upper clamping-j aw J is provided with aguide-pulley J and is connected with the forward ends of thepulley-supporting member D by means of links K. By means of thisconnection when the device is tripped and the pulley-supporting membermoves down under the influence of the weight carried by thesling-pulleys the upper clamping-j aw is moved backward and downward andthe lower clamping-jaw moves backward with it and upward toward it. Theguide-pulley J is simultaneously moved upward. In this way the rope isbent from a straight line or kinked by the clamping-jaws, which in thismanner obtain a very firm hold thereon. Just as the jaws are closing onthe rope they are both moving backward with the rope, and as a resultthey have a firm hold thereon before they stop and bring it to rest. Bythis means abrasion of the rope by the clamping mechanism is verygreatly decreased.

This concludes the description of such portion of my device as willnecessarily be described to give a thorough understanding to thoseskilled in the art. The hand tripping mechanism and swiveling mechanismhere illustrated are fully described in the application above referredto and require no detailed description at this point.

I realize that considerable variation is pos sible in the details ofthis construction without departing from the spirit of the invention,and I therefore do not intend to limit myself to the specific formherein shown and described.

I claim as new and desire to secure by Letters Patent 1.
